The Murdoch Children's Research Institute is recruiting patients for a new national trial aiming to identify those at risk of heart damage following cancer treatment.

The Australian Cardio Oncology Registry (ACOR)/Bio-bank study, a national first and the largest of its kind in the world, is recruiting across 12 hospitals for all current or previously treated patients exposed to therapies that can damage heart tissue, like chemotherapy, radiotherapy and immunotherapy. Cancer survivors can be of any age, including children, adolescents and adults.  

Anti-cancer therapies successfully treat 80 per cent of children with cancer but can cause heart disease in many survivors.

Childhood cancer survivors are 15 times more likely to have heart failure and eight times more likely to have cardiovascular disease than the general population. This high incidence rate makes cancer therapy-related cardiac toxicity the most significant cause of long-term disease and death in cancer patients. 

Associate Professor Rachel Conyers, a paediatric oncologist at Murdoch Children's, said these high numbers of "treatment-related deaths" were unacceptable and called for a major change in the management, diagnosis, treatment and monitoring of cancer therapeutic-related cardiovascular diseases. 

She said anthracyclines, a particularly cardiotoxic drug used in chemotherapy treatment, were used to treat more than 70 per cent of childhood, adolescent and adult cancers. 

"Anthracyclines have boosted childhood cancer survival rates dramatically," Associate Professor Conyers said. "But anthracyclines can have irreversible and sometimes fatal side effects, with up to 7 per cent of patients developing severe heart complications." 

The ACOR/Bio-bank study is trying to find clues (biomarkers) in genetics and heart imaging studies to reveal which children are vulnerable to heart damage if treated with cancer drugs.

"Heart imaging and finding predictive biomarkers will help move the standard of care towards more personalised medicine and reduce cancer therapy-related cardiac diseases," Associate Professor Conyers said. "These changes will improve the long-term quality of life of cancer survivors."

ACOR is guided by Associate Professor Conyers together with a national steering committee of 24 leaders in cardio-oncology health.

"Our ultimate goal is that after a child is diagnosed with cancer, we would immediately run a genetic test to see if they are at risk of heart damage. We will then be able to use protective medications." 

ACOR has provided a platform for discovering new cardio-protective medications, and will also pave the way for new cardio-oncology clinics across Australia to better prevent, detect, monitor and treat cancer patients with, or at risk of, cardiovascular disease. 

The team, which includes Murdoch Children's stem cell biologist Associate Professor David Elliott, has previously studied blood samples from 300 children treated with chemotherapy at The Royal Children's Hospital and Monash Children's Hospital. 

"These blood samples allowed us to begin analysing the child's genomics, to pinpoint genetic variations that may explain heart toxicity," he said. "We're narrowing the genetic field, but we need to look at more patients to be absolutely certain about which genes are involved."

Associate Professor Elliott said, importantly, ACOR would have a parent and patient advisory group to actively improve care and raise awareness about cardiovascular health for affected families. 

"We need to understand what patients' families require to feel cared for during and especially after treatment," he said. 

"We are confident that this national approach that includes patients, their families, researchers and doctors will improve the heart health of cancer survivors." 

Heart Foundation chief medical advisor Professor Garry Jennings said, "Australia has one of the highest cancer survival rates in the world. The immediate focus is on surviving the cancer, but survivors' long-term health is also crucial.

"This important study will increase our understanding of what causes heart problems in people who survive cancer and may lead to more effective therapies to prevent and treat these cardiac complications," he said.\

The 'Australian Cardio Oncology Registry' study is funded by the Royal Australasian College of Physicians, The Royal Children's Hospital Foundation and The Kids Cancer Project. 

The partnership includes The Royal Children's Hospital, Monash Medical Centre, Peter MacCallum Cancer Centre, The Royal Melbourne Hospital, The Baker Heart and Diabetes Institute, The Children's Hospital at Westmead, The Children's Hospital at Randwick, Hunter New England Health Newcastle, Royal Prince Alfred and

Chris O'Brien Lifehouse, Queensland Children's Hospital, Perth Children's Hospital, Royal Hobart Hospital and The Women's and Children's Hospital South Australia.

About Murdoch Children's
The Murdoch Children's Research Institute is the largest child health research institute in Australia committed to making discoveries and developing treatments to improve child and adolescent health in Australia and around the world. They are pioneering new treatments, trialling better vaccines and improving ways of diagnosing and helping sick babies, children and adolescents. It is one of the only research institutes in Australia to offer genetic testing to find answers for families of children with previously undiagnosed conditions.
